--- Comment #5 from chandra <chandra.konduru at intel.com> ---
Based on kernel logs attached to the bug, there is a request to do plane
scaling along with colorkey. Because skl hw doesn't support plane scaling and
colorkey at the same time, request is failed which is expected behavior. 

To make it work, either we need to give up colorkey or scaler support when both
are requested on a plane. To xv operate, allow colorkey continue to work
without using scaler. Then behavior would be similar to platforms without plane
scaler support. In this approach driver avoids failure by keeping src==dst by
fudging them. Working with Ville reviewing this approach to address the issue.

By the way, I am not able to reproduce the issue with mp4 file with single eDP
display. Need couple clarifications on reproducing:
1) Is issue happening only with 3 displays? or with any of 1 or 2 displays too?
2) What 3 displays output ports and sinks are you using? Are they in clone or
independent heads?
3) What is the kernel version?
4) can you attach the clip that you are using?
